Native and Invasive Species Education

Long Island is home to many native bat species. Nassau County SWCD recently planted a Bat Box in Pond Park, Great Nech Estates.


Once established this will provide a vital habitat for native Little Brown Bats (Myotis lucifugus). Native bat species help control populations of mosquito, beatles and other pests, a single little brown bat can catch 600 mosquitoes in just one hour! Bats also help with polination 

Permeable Pavement 

The Nassau County Soil & Water Conservation district helped install Permeable Pavement at the Bayville Community Center. 


This project was made possible due to a grant from the National Fish and Wildlife Foundation. Permeable pavement allows for the infiltration of storm water and helps protect an area from flooding. Ground water infiltration is especially important on Long Island as we rely on our underground aquifers being recharged.
